        Don't assume that egrep and fgrep exist.  POSIX 1003.1-2001 no
        longer requires them; you're supposed to use grep -E and grep -F
        instead.  Also, don't assume that "test -a" works, since POSIX
        doesn't require it.

        _LT_AC_LANG_CXX_CONFIG, AC_LIBTOOL_SYS_GLOBAL_SYMBOL_PIPE,
        AC_LIBTOOL_PROG_LD_SHLIBS):
        egrep -> grep, when that makes no difference.
